That's the hypothesis that these basic income trials are hoping to prove. Do people suddenly start working, even if they don't have to?
I think it's also a matter of community. If you suddenly get a basic income and your friends don't, you might get pretty lonely and bored. Whereas if you had lived for a longer time with a larger community of people who don't have to sell their labor, you might find yourself engaged in projects you wouldn't have invented yourself.
